If I understand your question correctly, I think I may have your answer in this blog post: https://evowebdev.com/2017/05/using-a-dropdown-menu-to-filter-a-custom-post-type-with-custom-taxonomy/ This solution specifically uses select form element auto-populated with taxonomy terms to sort CPT posts (ie, rather than presorting posts with pre_get_posts, it lets site visitors sort by the taxonomy term[s] they select).
